CROSS-REFERENCE TO RELATED PATENT APPLICATIONS

This patent application claims the benefit of U.S. Provisional Patent Application No. 61/530,445, filed Sep. 2, 2011, the entire teachings and disclosure of which are incorporated herein by reference thereto.

FIELD OF THE INVENTION

This invention generally relates to packaging and more specifically to packaging for water balloons.

BACKGROUND OF THE INVENTION

Water balloons are a mainstay in various recreational activities including social gatherings and games. Despite their popularity, however, introducing water balloons into any social event can be a daunting task given that the balloons must first be filled with water, and given that usually a large quantity of water balloons is required for an enjoyable experience. As an unfortunate result, water balloons are often omitted from an event when the task of filling them is taken into consideration.

As such, a niche has developed wherein water balloons are sold pre-filled to consumers. This niche has extended into mail order sales. However, current shipment methods do not provide a reliable solution for shipping water balloons without breakage of one or more the water balloons. Such breakage can cause water damage to the packaging of the water balloons as well as damage to adjacent packages. Therefore, there is a need in the art for a packaging unit and methods related thereto that will substantially reduce or entirely eliminate the risk of breakage of the water balloons during shipment.

The invention provides such a packaging structure and methods. These and other advantages of the invention, as well as additional inventive features, will be apparent from the description of the invention provided herein.

BRIEF SUMMARY OF THE INVENTION

In one aspect, the invention provides a filled water balloon packaging unit for containing filled water balloons in a tightly packed cluster. By holding the filled water balloons in said cluster, the risk of breakage of any one of the water balloons during shipment is substantially reduced or eliminated entirely. The packaging unit includes a packaging structure and filled water balloons. The packaging structure is transitionable between a finished and an unfinished state. In the finished state, the packaging structure includes an evacuated region and a non-evacuated region separated by a seal boundary. In certain embodiments, the seal boundary is a heat seal.

Other aspects, objectives and advantages of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

Turning now to the drawings, there is illustrated in FIG. 1 an exemplary embodiment of a packaging structure 20 containing filled water balloons 22. The packaging structure 20 and water balloons 22 together form a water balloon packaging unit 24. As will be described in greater detail below, the water balloons 22 are vacuum sealed within the packaging structure 20 such that they are forced into a tightly packed cluster.

As used herein, the term “cluster” is used to define a tightly packed grouping of filled water balloons wherein any one of the filled water balloons is not capable or substantially incapable or substantially prevented from relative motion between or separation from the remaining water balloons forming the cluster. Further, as used herein, the word “substantially” shall mean to a great extent, but not entirely.

The cluster configuration is advantageous to the extent that it substantially reduces or eliminates breakage of the filled water balloons 22 during shipment because the water balloons 22 are maintained in the cluster formation by the packaging structure 20 as explained below.

It will be recognized that the particular size and shape of the water balloons 22 is for exemplary purposes only and is not limiting on the invention. Indeed, the illustrated water balloons 22 are filled with approximately 10 to 30 ounces of water. However, in other embodiments, other volumes of water can be carried by the water balloons 22. A typical packaging structure 20 can carry a variety of amounts of water balloons 22. These amounts will vary depending upon the packaging structure 20 size and the size of the filled water balloons 22 carried thereby. It is contemplated that standardized amounts can be carried by a particular packaging structure 20 for ordering purposes. As an example, the filled water balloons 22 may be provided in 10 count, 20 count, 25 count, 30 count, 40 count, 50 count, 75 count, or 100 count quantities in any given packaging structure 20. However, it will be recognized that the lot sizes are for exemplary purposes only and other lot sizes are contemplated.

The water balloons 22 may be made from a latex material or alternatively a biodegradable latex material. However, latex-free materials are also contemplated.

The packaging structure 20 is illustrated in FIG. 1 in a finished state wherein it has been vacuum sealed to form the shipping unit 24. The shipping unit 24 tightly holds the cluster of filled water balloons 22 as illustrated. As one exemplary embodiment, the packaging structure 20 can be a two-ply vacuum sealing bag formed from nylon and polyethylene materials. The packaging structure 20 has a wall thickness about 1 MIL to about 5 MILs in the illustrated embodiment. The packaging structure can assume a variety of outer dimensions and thus any particular dimension is not limiting on the invention. However, as an example of typical sizes of packaging structures 20, the same can be supplied with an overall length dimension “L” of about 4 inches to about 24 inches and a width dimension “W” of about 4 inches to about 24 inches (see FIG. 2).

The packaging structure 20 is illustrated in the finished state at FIG. 1. As used herein, the phrase “finished state” means that all air has been evacuated by vacuum from an evacuated region 34 of the packaging structure. The evacuated region 34 is bounded by the outer edges of the packaging structure 20 and a seal boundary 32 formed therein. As will be described in greater detail below, the seal boundary 32 is a heat applied seal wherein the packaging structure 20 is fused to itself or fused to itself in addition with a chemical substance applied to the interior surfaces of the packaging structure 20 at the seal boundary 32 to enhance the heat sealing effect. Also illustrated at FIG. 1, on the other side of the seal boundary 32 is an end region 36. The end region 36 is non-evacuated and can function as a handle for the shipping unit 24 formed by the packaging structure 20 and the filled water balloons 22. Additionally, the end region 36 can include other structural features such as holes and/or grommets to hang the shipping unit 24 from a retail merchandise hook or the like.

With reference now to FIG. 2, the packaging structure 20 is shown in an unfinished state. As used herein, the phrase “unfinished state” means a state in which the packaging structure 20 has not undergone the vacuum sealing process. As shown at FIG. 2, the packaging structure 20 best resembles a bag in the unfinished state. The packaging structure 20 includes an opening 40 at an end thereof for loading the packaging structure 20 with the filled water balloons 22 prior to the vacuum sealing process.

Turning now to FIG. 3, the packaging structure 20 is illustrated within a vacuum chamber 52 of a vacuum sealing apparatus 50. It will be recognized that various styles of vacuum sealing apparatuses could be employed and thus the illustrated vacuum sealing apparatus 50 is not limiting on the invention. Once positioned within the vacuum chamber 52, the end of the packaging structure 20 is pulled into proximity with a sealing arrangement 54 used for forming the seal boundary 32 illustrated at FIG. 1.

Turning now to FIG. 4, a lid 56 of the vacuum sealing apparatus 50 is then closed to draw a vacuum on the packaging structure 20 and subsequently form the seal boundary 32 (see FIG. 1) therein. This vacuum may be on the order of −0.1 MPa to about −0.5 MPa. However, those skilled in the art will recognize that other vacuum ratings are possible depending upon packaging structure 20 size as well as the size and rating of the vacuum sealing apparatus 50. Generally, any vacuum rating is acceptable so long as it is not to an extent that it bursts the water balloons 22 within the vacuum chamber 52.

Turning now to FIG. 5, the lid 56 can incorporate a viewing window 60 to allow an operator of the vacuum sealing apparatus 50 to monitor the filled water balloons 22 during the vacuum sealing process to ensure that none have broken. Once a sufficient vacuum has been drawn upon the packaging structure containing the filled water balloons 22, the sealing arrangement 54 applies the aforementioned heat seal to form the seal boundary 32 (see FIG. 1).

Turning now to FIG. 6, once this heat seal is formed, the lid 60 (see FIG. 5) of the vacuum sealing apparatus 50 is open to access the packaging structure 20 in its finished state within the vacuum chamber 52. With reference to FIG. 7, the packaging structure 20 and filled water balloons 22 which now form the shipping unit 24 are removed from the vacuum sealing apparatus 50. At this stage, the aforementioned additional structures can be implemented into the end region 36 (e.g. holes, grommets, etc.).

Turning now to FIG. 8, once the aforementioned steps are completed, the finished shipping unit 24 is then placed in a shipping container 70. The shipping container 70 is generally a box structure that can take on a variety of dimensions depending upon the size of a particular shipping unit 24 and the number of shipping units 24 to be placed within the shipping container 70. The shipping container 70 is then sealed and shipped to a customer. From inspection of FIG. 8 it will be recognized that the shipping unit 24 generally assumes the clustered shape of the filled water balloons 22. As a result, relative movement of each water balloon 22 to the other water balloons 22 within a particular shipping unit 24 is substantially reduced or eliminated entirely. Advantageously, reduces the likelihood that the filled water balloons 22 will move about within the shipping container 70 and break during shipment to a customer. Additionally, and also due to the clustered shape of the filled water balloons 22, each shipping unit 24 presents a generally unitary fluid-like structure that permits the absorption of shock and other impact across all of the clustered water balloons 22 as opposed to any single one of said water balloons 22. This also reduces or eliminates the likelihood of breakage during shipment.
